one year in office..........

As of today have completed one year in office as Assistant Manager!! ye.................
Been through calm waters and rough seas! really calm and rough ones!
I really need someback from my colleagues as to how me have performed, where me need to improve. My manager is not a person who will state that me did not do this, this, and this. He would just state,just one or two things which me need to improve. Me more concerned abt areas where me have gone wrong in the past one year. Also very much concerned abt my communication skills. This is my weakest area, me suppose. Also need to more effective in my oral communication.
